THOMAS LIGHTBODY, OF YOUNGSTOWN, OHIO.

CAR-UNLOADER.

Application filed January 27, 1910.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I,'TrionAs IJIGHTBODY, a citizen of the United States,residing at Youngstown, in the county of Mahoning and State of Ohio,have invented certain new and useful Improvements in Car-Unloaders, ofwhich the following is a specification.

The object of this invention is to provide simple and highly efficientmeans for discharging the contents of an open freightcar at the side ofthe track and preferably in a wagon or other vehicle.

The invention will be hereinafter fully set forth and particularlypointed out in the claims.

In the accompanying drawings, Figure 1 is a transverse sectional view ofa freight car showing my improvements, parts being indicated in dottedlines. Fig. 2 is a view from one side of the car, with parts brokenaway. Fig. 3 is a similar view from the opposite side of the car.

Referring to the drawings, 1 designates an open top freight car, and 2,2, rails extending transversely of the box or body of the car andsupported by the sides thereof, preferably at or near the center. Eachrail is preferably composed of two channel-bars and between these barsare located spacedapart rollers 3, the diameters thereof being less thanthe height of the bars.

a designates a superposed box which is located and designed to movetransversely of the car box or body, being provided on its underside,along its edges, with square rods 5 which fit between the channel barsand rest on rollers 3. The length of this box 1 is ordinarily somewhatless than the width of the car body, while its width is considerablyless than the length of the car body so that material may be suppliedthereto from both sides thereof.

To the bottom of the box, at each side, are secured depending stops 6which, by engaging the outer and central rollers 3, limit the outwardand inward travels of the box.

When the box is moved outwardly to overhang the side of the car body andis tilted to empty its load, the extent of its inclination is controlledby chains 7 secured to the box and rails.

The box at its outer end is provided with an outwardly swinging door 10which is hung at its upper end but is normally held closed by a crankrod 12 passed longitudinally beneath the box and at its outer endengages the lower end of the door, the handle-end 13 of said crank rodbeing adjacent to the inner end of the box and within easy control ofthe operator.

At the side of the car, opposite to that from which the contents are tobe discharged, I provide two posts 141, secured to such side, andprojected upwardly between the channel-bars composing the rails. Thelatter are adjustably secured to such posts by pins 15 passed throughcoincident openings in the rail-bars and the posts. By this means theoperator may raise or lower the rails to conform to inequalities of thedriveway along the side of the track, the inclination of the car, or theamount of the load.

In practice, the box is normally extended transversely of and above thecar body so that laborers standing in the latter at either side of thebox may readily fill the latter from the car, and thereupon the box ismoved transversely of the car body to project considerably beyond theside thereof. The box is then tilted, but is limited in its movement bythe stop chains. The operator thereupon turns the handled end of thecrank rod and releases the door and permits the contents of the box tobe discharged into a vehicle at the side of the track.

The advantages of my invention are apparent. It will be seen that bymeans thereof the contents of a car may be readily placed in the box anddischarged into a vehicle at the side of the car, or it may be intoanother freight car on a lower plane.

I do not confine myself to the exact means shown and described forcarrying out my invention.

I claim as my invention 1. In combination with a car having an open topbody and a track extending transversely of and supported by the sides ofsuch body, a box arranged at right angles to the car body and of lesscapacity than such car body for receiving portions of the contentsthereof, said box being movable on said track and normally extendingacross the car body from side to side thereof, and capable of beingmoved longitudinally, transversely of the car body, to project beyondone of the sides thereof, and a stop for limiting the outward movementof the box.

2. In combination with a car having rails extended transversely thereofintermediate its ends, and rollers supported by said rails, a box ofless capacity than the car for receiving portions of the contentsthereof, said box being movably supported on said rollers, a stopcarried by said box engaging said rollers to limit the travel of thebox, and means for limiting the inclination of the box when projectedbeyond the side of the car.

3. The combination with a car having rails extending transverselythereof, and rollers supported by said rails, of a box mounted on saidrollers, a swinging gate at the outer end of said box, means at theinner end of said box for releasing said gate, and means for limitingthe outward movement of the box transversely of the car.

4. The combination with a car having rails extending transverselythereof, and rollers supported by said rails, of a box movable on saidrollers, stops carried by said box for limiting the outward and inwardmovements of the box, a gate at the outer end of said box, means at theinner end of the box for releasing said gate, and stop chains connectingthe box to the rails.

5. The'cornbination with a car, of rails extending across the topthereof intermediate its ends, means for regulating the inclination ofsuch rails relatively to the car, a box of less capacity than the carfor receiving portions of the contents thereof, said box being movableon said rails, and means for limiting the inclination of said box whentilted at the side of the car.

6. The combination with a car, of rails extending across the topthereof, posts atone side of the car, means for adjustably connectingthe rails at one end to said posts, a box movable on said rails, andmeans for limiting the inclination of said box when tilted at the sideof the car.

In testimony whereof I afiix my signature in presence of two witnesses.
